LEVELING DEVICE FOR THRESHING-MACHINES.

Specification o Applicationfiled February ica, residing at Scranton, in: the county of Bowman and State of North Dakota, have invented new and useful Improvements in Leveling Devices for ThreshingdVla-chines, of which-the following is a. specification.

This invention relates to leveling devices for threshing machines and grain separators, and it has for its objects to provide a simple and efiicient device of this character.

A further object of the invention is to provide a simple and etlicient leveling device which, after the desired adjustment has been eilected, may be securely locked to prevent accidental displacement or disarrangement when the threshing machine to which it is applied is in'operation.

\Viththese and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel,

arrangement and combination of parts be hereinafter fully described and particularlypointed out in the claims. In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited,

but that changes, alterations and modifications within the scope of "the claims may be resorted to when desired.

in the drawing, -Figure 1 is a side elevation showing a portion of the casing of a to which the invention-has beenapplied. Fig.'2 is'a rear elevation of the same. 3 is a vertical sectional view taken on the plane indicated by the line 3-3 in Fig. 1. Fig. at is a horizontal sectional view taken on the plane indicated by the line 1-4; in Fig. 3. Fig. 5 is a detail View oft-he wrench detached.

Corresponding parts in the several figures are denoted by like characters of reference. The present invention maybe applied to and used in connection with one or more of the supporting wheels of a threshing machine or grain separator. In the illusti'ation it has been shown as applied in connection with the hind wheels 1 of a threshing machine or separator, the casing of which is shown at 2.: Secured upon the sides of the casing 1 are plates 5 having sleeves i for the passage of screw threaded rods or bars 5 which slidably engage said sleeves. The screw threaded rods 5 sions 6 of non-circular cross section 1 which are guided through slots? in guide plates 8 secured upon the sides of the casing near the upper end of the latter. The screw threaded. rods 5 also have downward nonthreaded extensions 9 which are guided through slots 10 in guide plates 11 which are secured upon the underside of thebottom of the casing. The unthreaded extensions 9 of the screw threaded rods 5 are provided near their lower ends with laterally extending spindles 12 upon which the wheels 1 are supported for rotation. 7

Each of the screw threaded rods 5 is equipped with a nut 13 having a circular flange 1-1 supporting the sleeve a through which the threaded rod 5 being also partly or recess 15 in the side of the casing 2. The nut is provided upon. its upper side .with a boss or projection 16 upon which a wrench said handle being provided with a downwardly extending tooth 18 adapted to engage any one or a plurality of notches 19 formed in the flange 14 of the nut. It will be seen that the nut may be turned by means of the handle or wrench member, thus effecting vertical adjustment of the separator the sleeve 4, the nut being vertically movable upon thescrew threaded-rod 5, the extension 9 of which carries the supporting wheel. In this manner the casing of the threshing machine may be quickly and efiectively adjusted .to a perfectly level position, irrespective ofthe rough and uneven or hilly condition of the ground.

The side of the thresher casing has a laterally extending arm 20 carrying a pivoted latch member :21. Whenthe desired adjustment of the thresher casing has been effected, the wrench or handle is lifted to disengage the tooth 18 from the notches in the flange, after which it is turned about the axis of the screw until it lies adjacent to the side of the casing, atter which the said handle is depressed to place thetooth in engagement with the nearest notch in the flange of tee nut. The wrench or handle may then be secured against accidental movement by the latch member .21 connect-ed with the arm 20.

From the foregoing descr iption, taken in have upward extenslides. said flange accommodated in a notch member or handle 17 is loosely mounted,

casing which is supported upon thenut by' connection with the drawing here-to annested, the operation and advantages of this invention Wlll be readily understood. The

construction is simple; the device may be easily applied to threshing machines and separators-of various types or patterns, and the invention will be found eiiicient for the purposes for which it is provided.

Having thus described the invention, what,

sion' being of non-circular cross section;

slotted guide plates for tlie extensions of the screw threaded rod, a wheel carrying spindle assoclated with the downward extension of the screw threaded rod a nut en gaging the screw threaded rod below the sleeve'upon the casing which' 'is thereby supported, said nut being provided with a notched flange; and a wrench member connected with the nut for i'otatioirand having a tooth adapted to engage the notched flange.

the machine, a screw threaded rodislid'able vertlcally through sald sleeve and having vided with a wheel carrying spindle, guide members for's'aid extensions, a nut engaging the threaded rod below the sleeve which is thereby supported, a wrench member connected for rotation with the nut and having means to engage said nut to rotate the latmachine,;an'd a latch member pivotally con-: nected with said arm and adapted to engage the wrench member to lock the latter against movement.
